Don’t astronauts in general have to be fit as a fiddle?
I have a seriously, morbidly obese friend. I figure that underneath all that fat is the muscle of a body-builder.
She literally carries around a Ninja 250 everytime she walks.
So if Nasa can bring up a normal sized astronaut, but each astronaut could bring their sport bike with them.. that’s the same launch cost math for the same payoff.
